Colorimetric GTPase分析套組 |貨號602-0121(含PiColorLock)(abcam ab270553)
602-0121 High Throughput Colorimetric GTPase Assays


Innova Biosciences 提供之GTPase分析套組,可探討酵素活性是否扮演transport、signal transduction、protein biosynthesis及Cell differentiation之角色。應用於GTPase活性分析,提供high-throughput screen 大量GTPase inhibitor。可建立快速藥物篩選系統。採用PiColorLock™超高靈敏度Malachite green磷酸根呈色方法,分析GTPase酵素活性,克服傳統呈色方法、低靈敏度限制。GTPase酵素分析套組,包括stabilizing solution,可避開acid labile substrate所造成的高背景值,其背景值很低(1mM)。其分析波段為600-660nm,避開一般colored compounds之干擾。Pi-dye複合物極為穩定,其訊號強度可維持數小時之久。適用於大部份的assay buffer。蛋白質濃度高時,不會抑制顏色的形成。
PiColorLock™磷酸根檢測試劑,為檢測無機磷酸根(Pi)之含量;使用Malachite green磷酸根呈色法。可用於測量產生Pi的任何酶,包括ATPases、GTPases, phosphatases、熱休克蛋白及DNA解旋蛋白。PiColorLock™的獨特配方提高了測定線性,動態範圍和顏色穩定性;也可以用PiColorLock與不穩定的底物(例如ATP,GTP)一起使用,所述底物與其它酸性染料基檢測試劑產生高的非酶背景信號。此產品不具放射性應用Malachite green磷酸根呈色法,為高靈敏的磷酸根偵測試劑,確保穩定的綠色dye-phosphate複合物產生,避免發生受質非酵素水解干擾造成的背景雜訊。偵測範圍廣,可減少樣品稀釋的必要。
| Features | Benefits |
| Colorimetric assay | Simple, scalable and non-radioactive |
| Compatible with almost any assay buffer | Flexibility over a wide range of existing assays |
| Stable reagent formulation | Long shelf life |
| Unique accelerator | Speeds up color development |
| Unique stabilizer | Suppresses non enzymatic backgrounds with acid-labile substrates (ATP or GTP) |
| PiColorLock™-Pi complex is very stable | No precipitation, results can be measured over several hours – ideal for HTS |
| Wide linear range | No inhibition of color development by high concentrations of protein |
All crude extracts of tissues and cells will contain free phosphate unless steps have first been taken to remove it.
Note: ** Very low concentrations of detergent (0.002-0.005%) may cause precipitation. If a detergent is needed, use a concentration of >0.03%. Tween 20 is usually a good choice.
